FIELD OF THE INVENTION
The present invention relates generally to medical equipment. More
particularly, the
invention relates to a table mount for use with a shoulder press that
positions patient's
shoulders during medical procedures.
BACKGROUND OF THE INVENTION
Best practices demand correct visualization of the vertebrae intraoperatively
for all
surgical approaches involving the cervical spine. The Citow Cervical
Visualizer (CCV) has
proven to be a safe and effective means by which a spine surgeon can correctly
ascertain that
surgery is being performed at the correct level, thereby significantly
diminishing the
possibility of wrong site surgery in the cervical vertebrae. The CCV is a
handheld radiolucent
shoulder positioning device, or shoulder press, designed to facilitate and
optimize the
visualization of the cervical vertebrae during surgical approaches by moving
and holding the
CA 02727916 2014-12-16
shoulders out of the way in order to visualize an additional two to three
vertebrae.
Accomplishing this task via the usage of a pair of radiolucent carbon fiber
pusher tubes that
terminate in matched radiolucent arches, the CCV utilizes an adjustable
horizontal crossbar
tipped with ergonomic handgrips to transmit the necessary 24 to 37 pounds of
motive force
upon the patient's shoulders (i.e., the Acromion Clavicular joint)
facilitating the transient
movement of these structures and thereby allowing optimized visualization of
the cervical
vertebrae under X-Ray. The utilization of the CCV in this modality is effected
by a live
operator positioned at the head of the surgical table delivering this motive
force thru handheld
positioning and manipulation. Thus, the live operator is exposed to radiation
from the X-Rays,
which is an undesirable consequence of using the CCV. Furthermore, the CCV is
often used
in a complex surgical environment comprising a multitude of leads, lines and
monitoring
equipment around which the operator must maneuver, which may be a very
difficult task.
In view of the foregoing, there is a need for improved techniques for
providing means
for using a shoulder press such as the CCV on a patient without a live
operator that may be
easily employed in a complex surgical environment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention is best understood by reference to the detailed figures
and
description set forth herein.
8
CA 02727916 2014-12-16
Embodiments of the invention are discussed below with reference to the
Figures.
However, those skilled in the art will readily appreciate that the detailed
description
given herein with respect to these figures is for explanatory purposes as the
invention extends
beyond these limited embodiments. For example, it should be appreciated that
those skilled in
the art will, in light of the teachings of the present invention, recognize a
multiplicity of
alternate and suitable approaches, depending upon the needs of the particular
application, to
implement the functionality of any given detail described herein, beyond the
particular
implementation choices in the following embodiments described and shown. That
is, there are
numerous modifications and variations of the invention that are too numerous
to be listed but
that all fit within the scope of the invention. Also, singular words should be
read as plural and
vice versa and masculine as feminine and vice versa, where appropriate, and
alternative
embodiments do not necessarily imply that the two are mutually exclusive.
The present invention will now be described in detail with reference to
embodiments
thereof as illustrated in the accompanying drawings.
Preferred embodiments of the present invention provide a table attached
device, or
universal table mount, for a shoulder press that provides a firm and stable,
horizontal cradled
platform upon which the shoulder press can travel and lock in such a way as to
effectively and
consistently replicate the action and application of sustained force for the
duration of an X-
Ray, which would otherwise be delivered by a live operator. By providing a
generally
consistent and reliable platform, the table mount allows for the reliable and
correct
positioning and quick release of the shoulder press without the necessity or
presence of a live
operator during the actual patient X-Ray, thereby generally eliminating the
possibility of
exposure to radiation for all personnel. Without a table mount according to
preferred
embodiments, the handheld nature of the shoulder press device offers no such
protection and
precludes the use of the shoulder press device in environments where a C-ARM
(i.e.,
Intraoperative Flouroscope) is utilized due to harmful exposure levels.
Additionally, by
providing a stable platform for the shoulder press throughout the entire
duration of a surgical
procedure, the table mount allows for one time set-up and continuous
positioning of the
9
CA 02727916 2014-12-16
shoulder press in immediate proximity to the usage site, thereby generally
eliminating the
complicated procedure of maneuvering and positioning the shoulder press in the
ubiquitous
environment of leads, lines, anesthesia and monitoring equipment, as well as
greatly
simplifying the usage of the shoulder press without disturbing these sensitive
arrays.
However, alternate usages for preferred embodiments of the present invention
may be
conceived such as, but not limited to, usage in an X-Ray room, usage by
paramedics, usage in
the trauma specialty for diagnosis, usage by orthopedic surgeons as a surgical
positioner for
patient extremities during revision hip arthroplasty, etc. Further alternate
usages for preferred
embodiments of the present invention may also be conceived such as, but not
limited to, usage
in various surgical, diagnostic and imaging procedures as an anatomical
positioner for
applications throughout the entire human anatomy relating to all aspects of
patient care and
specialties. Yet other alternative usages for preferred embodiments of the
present invention
may also be conceived such as, but not limited to, usage relating to all
surgical specialties as a
platform for the positioning and manipulation of tools, equipment, and
necessities relating to
all aspects of patient care, including, but not be limited to, surgical,
diagnostic and imaging of
patients. It is further contemplated that alternate usages for preferred
embodiments of the
present invention may also be conceived such as, but not limited to, usages
relating to all
aspects of veterinary care.
Figure 1 illustrates an exemplary universal table mount 101 for a shoulder
press 103 in
use on a surgical table 105, in accordance with an embodiment of the present
invention. In the
present embodiment, table mount 101 is comprised of two distinct yet mirror
imaged sections,
a dedicated right section 107 and a dedicated left section 109. Alternate
embodiments may be
implemented in which the left and right sections of the mount are connected.
In the present
embodiment, right section 107 and left section 109 clamp onto surgical table
105, which is
equipped with industry standard accessory side rails 111 provided by table
manufacturers for
the use of the surgical staff in mounting various necessary equipment to
surgical table 105 for
use during surgery. Accessory side rails 111 may use American standard or
metric
measurements, and universal table mounts according to preferred embodiments of
the present
invention may be available in distinct clamping sizes to accommodate these
industry
standards. Right section 107 and left section 109 of table mount 101 slide
easily onto
CA 02727916 2014-12-16
accessory side rails 111, and an attachment mechanism 113 fully seats and is
secured with a
simple twist dial 115. Guide rails 117 extend from attachment mechanisms 113
onto which
upward supports 118 are slidably attached with slides 119. Attachment
mechanisms 113 are
preferably made of aluminum; however, the attachment mechanisms in alternate
embodiments
may be made of different materials such as, but not limited to, different
metals or plastic.
Guide rails 117 and upward supports 118 are preferably one-inch square
aluminum bars.
However, those skilled in the art, in light of the present teachings, will
readily recognize that
the mount rails and upward supports in alternate embodiments may be made in
different
shapes and sizes and be made of various different materials such as, but not
limited to,
different metals or plastic. Furthermore, slides 119 are preferably made of
plastic; however,
alternate materials such as, but not limited to, various metals may also be
used. In the present
embodiment, slides 119 comprise handbrakes 121 that enable upward supports 118
to be
locked into place on guide rails 117.
In typical use of the present embodiment, after mounting table mount 101 to
accessory
side rails 111, placement of shoulder press 103 within a shoulder press cradle
is quick and
easy, and shoulder press 103 is secured within the shoulder press cradle with
adjustable/pivoting L-Shaped restraints 123 provided to accommodate this
function. After
positioning and adjusting shoulder press 103 to the proper width to
effectively migrate the
shoulders distally within table mount 101, an operator may apply the 24 to 37
pounds of
motive force upon the Acromion-Clavicular joint with shoulder press 103 by
squeezing
handbrakes 121 and pushing upward supports 118 or shoulder press 103 toward
the patient on
surgical table 105. The application of motive force by the operator along with
the hand
actuation of handbrakes 121 advances the position of shoulder press 103. When
shoulder
press 103 is correctly positioned, the operator releases handbrakes 121 to
lock sliders 119 and
therefore shoulder press 103 in place. The operator may swiftly and easily
unlock and move
shoulder press 103 away from the patient by squeezing handbrakes 121 and
pulling back.
Some embodiments may also comprise a quick release mechanism for the
handbrakes so that
the shoulder press may be immediately moved away from the patient in case of
an emergency.
11
CA 02727916 2014-12-16
In alternate embodiments, the travel of the upward supports and the shoulder
press
within the shoulder press cradle along the guide rails is unidirectional
toward the patient. In
these embodiments the upward supports are able to move freely toward the
patient and are
prevented from moving away from the patient through the incorporation of an
internal friction
braking system. The actuation of a brake release allows for a reversal of
travel away from the
patient by releasing the internal friction braking system. The friction brake
resists all
backward motion due to tilting and comprises a hand control that reorients the
tilt by finger
tapping in order to enable backward movement. The friction brake preferably
uses a large
trigger somewhat akin to a bicycle handbrake lever. However, a bicycle brake
uses a caliper
style set of rubber pads whereas this friction brake uses no calipers, discs
or pads and instead
utilizes the slight offset of a channel and the guide rail of the table mount
to halt backward
motion unless the internal offset is lessened through application of the
trigger/brake release.
Other alternative embodiments may employ differing means for halting the
backward motion.
These other alternative means will also have at least one hand control means
for enabling
backward movement.
Figure 2 illustrates an exemplary mount 201 for a shoulder press 203 for use
on patient
surfaces without side rails, in accordance with an embodiment of the present
invention. In the
present embodiment, mount 201 comprises variable clamps 207 rather than
attachment
mechanisms for sliding onto an accessory side rail. Variable clamps 207 slide
over the edges
of a patient surface and are held in place by actuating plates 209 that
squeeze the edges of the
patient surface when clamp locks 211 are employed. In other alternative
embodiments clamps
may be locked into position by any number of devices such as, but not limited
to, levers, dials,
knobs, etc. that are deemed appropriate to the patient anatomy the alternate
embodiments
address. This enables mount 201 to be attached to surfaces other than
operating room surgical
tables with side rails for example, without limitation, other types of patient
beds and tables,
paramedic long boards, imaging tables, exam tables, etc., any other patient
care surfaces
unrestricted to unrestricted to horizontal positions, and whatever variable
geometry offered by
the patient care surface, whether fixed or movable during usage
12
CA 02727916 2014-12-16
Paramedics often carry patients on long boards, and when a patient has a
suspected
subluxation injury (i.e., broken neck), they are brought to the emergency room
(ER) on such a
long board and typically remain on this long board throughout the ER
experience. In typical
use of the present embodiment, shoulder press 203 may be attached to a long
board with
mount 201 to quickly assist in correct visualization of the cervical spine of
the patient to
determine if there is an injury.
Having fully described at least one embodiment of the present invention, other
equivalent or alternative methods of providing a table mount for a shoulder
press or
anatomical positioner according to the present invention will be apparent to
those skilled in
the art. The invention has been described above by way of illustration, and
the specific
embodiments disclosed are not intended to limit the invention to the
particular forms
disclosed. For example, the particular implementation of the table mount may
vary depending
upon the particular type of shoulder press used. The table mounts described in
the foregoing
were directed to implementations for use with the CCV; however, similar
techniques are to
implement table mounts for use with various different shoulder presses,
anatomical
positioners, equipment positioners, etc. Implementations of the present
invention
implemented for use with shoulder presses other than the CCV are contemplated
as within the
scope of the present invention. The invention is thus to cover all
modifications, equivalents,
and alternatives falling within scope of the following claims.
